Ms. miller decides to give a test worth 90 points and contains 25 questions. multiple-choice questions are worth 3 points and wo

schepotkina [342]

X= # of multiple choice questions
y= # of word problem questions

EQUATION 1:
x + y= 25

EQUATION 2:
3x + 4y= 90

STEP 1:
solve for one variable in equation 1

x + y= 25
subtract y from both sides
x= 25 - y

STEP 2:
substitute x=25-y in equation 2

3x + 4y= 90
3(25-y) + 4y= 90
75 - 3y + 4y= 90
75 + y= 90
subtract 75 from both sides
y= 15 word problems

STEP 3:
substitute y value to find x

x + y= 25
x + 15= 25
x= 10 multiple choice questions

ANSWER: There are 15 word problems and 10 multiple choice questions.

Hope this helps! :)

A. x = 1 is a solution.

C. x = –1 is a solution.

<h3>What is rational equation?</h3>

Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.

We can see then that:

$\frac{4}{x + 6} + \frac{1}{ {x}^{2} } = \frac{x + 10}{ {x}^{3} + 6 {x}^{2} }$
